BOOKKEEPERS STOOL.

SPECIFICATION forming part Of Letters Fatent No. 722,585, dated March 10, 1903.

Application filed December 6 1902.

To aZZ whom it may concern.-

Be it known that 1, ROBERT W. J EMISON, a citizen of the United States, residing at Macon,in the county of Bibb and State of Georgia, have invented new and useful Improvements in Bookkeepers Stools, of which the following is a specification.

This invention relates to what I shall for convenience term a bookkeepers stool, although it will be evident from the following description that it may be used with advantage by other workers; and the primary object of the invention is to provide a simple and efiective device of this character, includ ing a stool and a supporting-frame therefor having means for sustaining the stool for traveling movement, whereby said stool can be front of a desk or the like without the necessity of the user leaving the same.

The invention includes other objects and advantages, which, with the foregoing, will be set forth at length in the following description, while the novelty of the invention will form the basis of the claims succeeding said description.

Said invention is clearly represented in the accompanying drawings, forming a part of this specification, and in which- Figure l is a side elevation of a bookkeepers stool including my invention in one sim- 2 is a front elevation of the said stool. Fig. 3 is a plan view of the same.

Like characters of reference indicate like parts throughout the several views.

The improved device embodies in its construction a frame for supporting a stool for traveling movement, and said frame is illustrated as consisting in the present case of the duplicate end columns or uprights 2, which may be of any suitable material--such,-for example, as castings. The said columns or uprights 2 terminate at their lower ends in legs 3, provided with ball-bearing casters 4:, so that the supporting-frame and the parts carried thereby can be readily moved from place tovplace. The columns or uprights 2 are united at their front and rear by the rails 5, located one above the other and constituting tracks for receiving the wheels of the traveling stool-carriage. These rails 5 may Serial No. 134,195. (No model.)

I be made from any suitable material-for example, tubing or piping.

The ends of the rails are threaded to fit the nuts 6, the bodies of the nuts being cylindrical and being adapted to lie within circular depressions or pockets formed in the columns or uprights 2 and held therein by the clips 7, screwed or otherwise attached to said columns, it being seen that the clips where they engage the bodies of the nuts are curved to agree therewith, so that said nuts can be readily turned in order to properly connect the end columns or uprights. The outer sides of the nuts have squared extensions 8, by which said nuts may be turned by a wrench of other suitable tool.

The stool is denoted by 9, and it is provided with a seat of some suitable kind from the body of which the screw 10 depends, such screw passing through a nut 11 upon the upper side of the approximately rectangular carriage 12. The said carriage 12 is provided near its opposite ends with axles 13, provided at their outer ends with wheels 14 of some suitable kind peripherally grooved to receive the superposed rails 5. ripheries or tires of the wheels 14 are preferably of rubber or are otherwise cushioned, so that the wheels as they travel along the rails can do so noiselessly and without jar to the occupant of the steel or chair 9. The lower rails in each case might be considered the supporting ones, while the upper rails prevent tilting movement of the carriage as the same rolls back and forth upon the lower rails.

By means of the screw 10, depending from the body of the stool 9 and extending through the relatively fixed nut 11, said stool can be readily raised or lowered, as occasion may require.

The device is adapted for advantageous use by bookkeepers, draftsmen, and others who use high or stand-up desks or tables to accomplish their work, for the reason that the stool while it is occupied by the user can be readily moved from place to place along the supporting-rails 5 without the necessity of such occupant leaving the stool, by virtue of which much time is saved in certain kinds of work for example, in posting books.

I mount under the lower rails upon each The peside of the frame the rods 15 in parallelism with the rails, the opposite ends of said rods being threaded to fit the nuts 16, the cylindrical bodies of which are mounted for turning movement in the lower ends of the arcuate slots 17, formed in the end columns 2, and said nuts, like the ones hereinbefore described, have squared extensions 18, by which they can be readily operated in order to secure the rods in place. Truss-brackets are shown at 19, they being of approximately X shape and separated at suitable distance, their lower branches being equipped with sleeves to receive the rods 15,while the upper branches are concaved to receive the lower track-rails.

Upon the rods 15, between the lower branches of the braces 19, are fitted thesleeves of truss-brackets 20, which depend from said rods and are grooved at their lower ends to receive the truss-rods 21. The ends of the truss-rods extend through the columns or uprights 2 and are threaded to receive the nuts 22. The outer ends of the truss-rods, it will be seen, are deflected slightly upward, so that when the nuts 22 thereof are turned onto the same an upward stress is applied to the truss-rod which is transmitted to the rod 15, and thereby to the lower rails 5, through the intermediate truss-brackets 20 and braces 19, so as to prevent said lower rails from springing or buckling between their ends.

Upon the inner side of the frame or that side thereof which is next a desk or its equivalent is a foot-rest 23, consisting-of a bar coextensive with the rails 5 and terminating in the inwardly-extending arms 241, which fit against the inner faces of the columns or uprights 2. Bolts 25 extend through said arms 24 and also through vertically-elongated slots 26 in the columns 2 in order to provide for the vertical adjustment of the foot-rest. The rods 15 are united near their opposite ends by the braces or cross-pieces 27, provided at their extremities with sleeves to receive the said rails.

The frame, consisting of the columns or uprights 2, united by the rails 5 and rods 15, which latter are braced in the manner indicated, is a thoroughly stable structure, possessing means for preventing the buckling or bending of the rails upon which the stoolcarriage 12 is directly mounted.

The different parts hereinbefore described may be made of any suitable material. For example, as previously stated, I may make the columns or uprights 2 of castings and the rails 5 and rods 15 of tubing.

The frame is preferably connected with the desk or table, and the means shown for this purpose I will now describe.

To the braces 27, substantially centrally thereof, 1 pivot the outwardly-extending links 28, to the outer ends of which are likewise connected similar links 29, pivoted to a desk, table, or other support at their outer ends, such table or its equivalent being indicated diagrammatically and only in Fig. 3.

When the device is not in use, the frame can be pushed under a desk, and when it is desiredto employ the same it can be readily withdrawn therefrom. When the frame is under the desk, it is out of the way and it can be employed as a foot-rest. As the frame is connected with the desk, it can be readily moved from place to place therewith, and as it is equipped with casters it can be moved along a tiled, wood, linoleum, or carpeted floor without possibly injuring same. As the frame carries the track upon which the stool or chair 9 is mounted, it will be seen that such stool or chair can be moved along the front of thedesk without the necessity of mounting the same upon a track upon the floor, as in such case the track disfigures the floor and interferes with the usual arrangements of a mercantile or other establishment.

By means of the device a user occupying the stool or chair 9 and with his feet upon the rest 23 can by pressure upon said rest readily propel himself from place to place along the desk and with a very slight effort and without the necessity of using the hands for this purpose, so that the hands are left free and can be employed in posting books or for checking from one book to another or accomplishing other work requiring long desk-room, and as the wheels of the stoolcarriage are rubber-tired such carriage travels noiselessly. The stool or chair 9 not only has a rotary movement, but it is adjustable vertically to any desired height. The device, it will therefore be understood, is simple and effective, thoroughly strong, and advantageous for the purposes intended.

I do not limit the invention to the exact construction hereinbefore described, for any variations may be adopted within the scope of my claims.

It is evident that more than one of the traveling stool-carriages can be mounted upon the track in order to accommodate several persons, this being advantageous where a number of persons have to work at the same desk-for example, in railroad-offices.

Having described my invention, what I claim is- 1. In a device of the class specified, a frame consisting of columns, rails located one above the other uniting the columns at their front and rear, rods also uniting the columns below the lower rails, braces between the lower rails and rods, truss-rods below said other rods, the outer portions of which are deflected upward and extend through the columns and terminate in threads having nuts upon the outside of the column, and-truss-brackets between the truss-rods and the first-mentioned rods.
